The present invention relates to the use of 1-(4,4-dimethylcyclohexyl)ethanone, 1-(4,4-dimethylcyclohex-1-en-1-yl)ethanone, 1-(4,4-dimethylcyclohexyl)ethanol, 1-(4,4-dimethylcyclohexyl)ethyl acetate and 1-(2-hydroxy-4,4-dimethylcyclohexyl)ethanone as a fragrance substance, in particular with a flowery and/or fruity olfactory characteristic. The present invention further relates to fragrance compositions and perfumed products comprising the compounds listed above. The present invention also relates to a method producing perfumed products and a method producing 1-(4,4-dimethylcyclohexyl)ethanol or 1-(4,4-dimethylcyclohexyl)ethyl acetate. Further, the invention relates to the compounds 1-(4,4-dimethylcyclohexyl)ethyl acetate, 1-(4,4-dimethylcyclohexyl)ethanol and 1-(2-hydroxy-4,4-dimethylcyclohexyl)ethanone.
A method for imparting a flowery and/or fruity olfactory characteristic to a composition comprising adding a compound selected from the group consisting of 1-(4,4-dimethylcyclohexyl)ethanone, 1-(4,4-dimethylcyclohex-1-en-1-yl)ethanone, 1-(4,4-dimethylcyclohexyl)ethanol, 1-(4,4-dimethylcyclohexyl)ethyl acetate, and 1-(2-hydroxy-4,4-dimethylcyclohexyl)ethanone to the composition in an amount sufficient to impart a flowery and/or fruity olfactory characteristic to the composition.
A fragrance composition comprising a compound selected from 1-(4,4-dimethylcyclohexyl)ethanone, 1-(4,4-dimethylcyclohex-1-en-1-yl)ethanone, 1-(4,4-dimethylcyclohexyl)ethanol, 1-(4,4-dimethylcyclohexyl)ethyl acetate, and 1-(2-hydroxy-4,4-dimethylcyclohexyl)ethenone, wherein the compound is in an amount sufficient to impart a flowery and/or fruity olfactory characteristic to the fragrance composition.
A method for producing 1-(4,4-dimethylcyclohexyl)ethanol or 1-(4,4-dimethylcyclohexyl)ethyl acetate comprising the following reaction step:
A method for imparting a flowery and/or fruity olfactory characteristic to a composition comprising adding 1-(4,4-dimethylcyclohexyl)ethyl acetate to the composition in an amount sufficient to impart the flowery and/or fruity olfactory characteristic to the composition.
